Chapter 6

Friction Vector lab

First, mass a wood block, and calculate it's weight.
Place the block on a ramp,
WHILE SLOWLY RAISING THE RAMP, tap the ramp until the block just begins to move. You want the constant velocity! (WHY would this be important?)
Then carefully measure the angle formed by the ramp and the table. Calculate the coefficient of sliding friction for the block-ramp surface!

Repeat several trials to confirm you have the angle correct.

Repeat the activity for the second block. Create a data table to organize your information.

Report: Each student turns in their own page(s) Show all formulas and work.

a. Construct a diagram that shows the ramp, angle between the ramp and desktop, and the block. Draw in and label the force vectors representing the weight of the block, and the components of that weight that act parallel (Fa)and perpendicular to the ramp, the Normal Force and the Frictional Force:

b. Determine weight, Fg, of each block, and the component of that weight that is parallel to the ramp (Fa), and the component that is perpendicular to the ramp.

c. Calculate the coefficient of sliding friction for each block.

d. Make a free-body diagram for each block.
